The RNeasy Mini Kit (Qiagen) was used to isolate total RNA from cells. For ChIP-seq, chromatin was fixed with 1% formaldehyde for 10 min and sheared in a sonification buffer. Fragmented DNA was incubated with primary antibodies overnight at 4℃ and then with Protein A/G Dynabeads for 1 h. The beads were collected and washed sequentially with the following solutions: high-salt buffer, low-salt wash buffer, and TE buffer. Elution of the immunoprecipitated protein/DNA complexes was performed using elution buffer at 65℃ for 4 h. Next, the protein/DNA complexes were incubated with proteinase K (Invitrogen) and RNase A (Invitrogen) for 1 h. De-crosslinked DNA was purified using the PCR Purification Kit (Qiagen). For ATAC-seq, in total, 50,000 cells were digested, collected, and lysed in ice-cold lysis buffer for 5 min. Then, Tn5 transposase reactions (Vazyme Biotech, TD501) were performed using the TruePrep DNA Library Prep Kit (Vazyme Biotech). RNA libraries were prepared for sequencing using NEBNext RNA first and second Strand Synthesis Module (NEB, USA) and KAPA Library Preparation Kit (KAPA Biosystem). The KAPA Hyper Prep Kit (Kapa Biosystems, KK8502) was used to construct ChIP-seq libraries for Illumina PE150 sequencing. For ATAC-seq library, the transposed DNA fragments were amplified and collected using the TruePrep DNA Library Prep Kit (Vazyme Biotech).
